/** SIP Header To.
 * The To header field specifies the desired
 * "logical" recipient of the request, or the address-of-record of the
 * user or resource that is the target of this request.  This may or may
 * not be the ultimate recipient of the request.  Like the From
 * header field, it contains a URI and optionally a display rtpmap.
 * <BR> A request outside of a dialog MUST NOT contain a To tag; the tag in
 * the To field of a request identifies the peer of the dialog.  Since
 * no dialog is established, no tag is present.
 * The original
 * recipient may or may not be the UAS processing the request, due to
 * call forwarding or other proxy operations.  A UAS MAY apply any
 * policy it wishes to determine whether to accept requests when the To
 * header field is not the identity of the UAS.  However, it is
 * RECOMMENDED that a UAS accept requests even if they do not recognize
 * the URI scheme (for example, a tel: URI) in the To header field, or
 * if the To header field does not address a known or current user of
 * this UAS.  If, on the other hand, the UAS decides to reject the
 * request, it SHOULD generate a response with a 403 (Forbidden) status
 * code and pass it to the server transaction for transmission. */
